While most people tend to assume that movie-making is a fun business, with millions of dollars being handed out left and right and everyone having a great time, the reality of cinema can actually be very different.
Some films are real nightmares to make, with executive interference, moody actors, egotistical directors, and bad ideas souring the entire experience for pretty much everyone concerned. In fact, some of the most famous films ever made had some shocking behind-the-scenes stories, with many cast and crew members keen to finish filming and move on to something else as quickly as possible.
In some cases, directors or producers bite off more than they can chew. In others, their personalities clash with the cast and crew around them. Either way, the result is a highly difficult production process in which most people are pretty unhappy to head to work each day and eager to see filming finally come to an end.
Some of these movies turned out great when they hit the cinemas, while others were critical or commercial failures. In each case, however, they certainly weren't a lot of fun to make.
